I2C TWI SPI Serial Interface Module

Description:

With the limited pin resources of Arduino controllers, integrating a normal LCD display along with multiple sensors or an SD card can be challenging. This I2C interface module simplifies the process by enabling data display using only 2 wires. For projects already utilizing I2C devices, this module adds no extra resource burden.

• Compatibility: HD44780 LCD interface compatible; suitable for 1602, 1604, and 2004 LCD modules
• Support: Compatible with many Arduino and Raspberry Pi libraries
• I2C Standard: Operates with just 4 wires – VCC, GND, Data, Clock
• Address Select: Features 3 pairs of solder pads for address selection
• Backlight Control: Includes a short pin for turning the LCD module backlight on and off
• Contrast Adjustment: Allows for adjustable LCD contrast

This module is ideal for projects requiring efficient use of pin resources while maintaining the functionality of an LCD display.
